Why did keyboard icon disappear?

I possess a HP Envy x2 15 with Windows 10 as the OS. Somehow after starting my laptop the keyboard icon (to make the touchpad keyboard appear) disappeared from the taskbar. Is there a keyboard shortcut to make the icon disappear (which I thus perhaps accidentally executed)?

Otherwise I find it highly peculiar that the icon disappear from the taskbar.

Lastly, is there a way to rearrange the icons on the righthand side of the taskbar (keyboard sign, volume, battery icon etc.)?
